Will Mark Brown be the next Prime Minister of the Cook Islands following the 2026 Cook Islands parliamentary elections?

The August 12, 2026 general election drives the current market pricing, with incumbent Prime Minister Mark Brown of the Cook Islands Party holding an 89% implied probability after leading recent preferred-leader polling at 35% amid 32% undecided voters. His position reflects the party’s 2022 parliamentary majority secured with independent support, combined with April 2026 stabilization of ties with New Zealand through a joint defense and security declaration plus resumed funding. Opposition figures such as Teariki Heather of the Cook Islands United Party and Tina Browne of the Democratic Party register single-digit odds consistent with lower polling shares and limited momentum shifts among key voter blocs. Late factors that could still influence outcomes before parliament convenes include turnout variations in specific electorates or post-election coalition negotiations.
